Feeding piglets in alive mass of 12 – 20 kg at intensive production of pork

Abstract

The purpose. To study influence of all-in-one feed for piglets in alive mass of 12 – 20 kg with minimum dose of calcium and phosphorus and the heightened dose of lysine, methionine + cystine and threonine on change of alive mass of piglets in the age of 41 – 60 days and productivity of feedstuff. Methods. Conventional zootechnical and analytical. Results. Use of all-in-one feed for piglets in alive mass of 12 – 20 kg with minimum dose of calcium and phosphorus and the heightened dose of lysine, methionine + cystine and threonine ensures deriving minimum alive mass of piglets in 60-day age at the level of 20 kg and average daily increase of alive mass for 400 g, and conversion of 1,75 kg of feed compound for 1 kg of increase of piglets. Conclusions. At use of all-in-one feed for piglets in alive mass of 12 – 20 kg with the heightened dose of lysine, methionine + cystine and threonine they observed a trend of decrease of expenditures of feed compound for the term of feeding piglets in the age of 41 – 60 days from 15 to 14 kg and lowering of its conversion for 1 kg of increase of piglets (from 1,9 to 1,75 kg) in comparison with the use of all-in-one feed with the standard content of the above indicated amino acids. The gained productivity indexes of piglets conform the requirements of intensive} production of pork and are characterized by positive economic efficiency.
